Developmental branch is underway (again).
Changed conversation_print and conversation_list so that conversations can be printed multiple times in one session.
Changes to development notes regarding adding a format_reset function.
Changed the way classification rules are read and payloads are filtered as a step toward allowing multple format/classification data sets created within a single run.  Also in anticipation of a GUI.
Turned warnings back on.  Fixed memory issues with output files to safely save multiple times in a single session.
Added support for reading formatting/classifications from text files.  However, the process functions hang on multiple passes.  Fixing this tomorrow.
Added labeling/formatting from files and setting the default label.
Merge branches 'developmental' and 'master'
Merged developmental and master after adding load-from-file for format and class rules.
